DEHORNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 644,350, dated February27, 1900.

Application iiled August 9, 1899.

To @ZZ whom, it 17mg concern:

Be it known that I, JERRY D. DEcELLE, a citizen of the United States,lresiding at Fort Collins, in the county of Larimer and State ofColorado, haveinvented anewand useful Dehorning Implement, of which thefollowing is a specication.

This invention relates to dehorning implements; and one object of thesame is to provide simple, efficient, and compact means for painlesslydehorning cattle by avoiding a crushing cut and regularly producing aseverance from the points toward the heels of the v cutters, and,further, to employ positivelyacting operating devices in connection withsaid cutters that have a forceful leverage.

Further objects and advantages will appear in the subjoined descriptionand as the invention becomes better understood. The preferred embodimentof the same is illustrated in the accompanying drawings, wherein similarnumerals of reference are employed to indicate corresponding parts inthe several views, and in which- Figure 1 is a perspective view of adehorningimplernentembodyingtheinvention. Fig. 2 is an elevation of thesame broken away, showing the parts open. Fig. 3 is a transversehorizontal section on the line x Fig. 2. Fig. 4 is a similar section onthe line y y, Fig. 2. Fig. 5 is a detail perspective view of a part ofthedevice, showing a slight change in the arrangement. j

The numerals 1 and 2 designate oppositelydisposed handle-levers havingterminal grips 3, which are preferably tubular and may be covered withany suitable material or have an integral surface construction toprevent slipping from the hands or to be easily grasped. The terminalsof the said levers opposite to those bearing the grips 3 are laterallyeX- tended or widened to provide heads 4f, each of which has a pair ofspaced ears 5 and 52' continuous therewith, the inner edge between saidears being concaved, as at 6, to afford a clearance when thehandle-levers are drawn inwardly adjacent other parts of the device. Theear 5a of each head l1 is pivotally fulcrumed between the outer ends ofa pair of tie-bars fi, which extend transversely across the implementand are similar in construcerating the handle-levers 1 and 2.

tion and have on their inner faces space-lugs 8 and antifriction-rollers9 in reverse position on the opposite bars and so thatthey will projectin opposite alternate directions. Two antifriction-rollers 9 areemployed, and each is closer to one of the bars than the other. Thespace-lugs S, near opposite ends of the bars 7 and in reverse positions,bear upon the ears 5f, the pivotal connection at this point beingestablished by means of rivets or analogous devices l0, held in the saidlugs and bars and passing through the said ears. The intermediatespace-lugs bear against opposite sidesof a contiguously-arranged pairofv cutter-Shanks 11, each having an inturned or directed terminal 12 atan angle to the shank proper, which is pivotally connected to the ear 5on each handle-lever, the terminals 12 being applied to reverse faces ofthe opposite ear 5. The Shanks 1l are also formed with longitudinalguide-slots 13, and beyond the terminals of the guide-slots, in thedirection of the working ends of said Shanks, the material is increasedin width to provideabroad bearing and serve as a rigid support for amain pivotbolt 14, inserted through said parts of the Shanks whenclosely arranged in operative relation.

The antifriction rollers 9 are rotatably mounted on rivets or pins '15,extending through the intermediate space-lugs 8 on the bars 7, and, aspreviouslyindicated, the said rollers are by this means held overagainst the inner faces of the opposite bars and iit and move in theguide-slots 13 of the shanks 11 and serve to ease the movement of saidshanks in opening or closing the same by op- Beyond their pivotalconnection the shanks 11 terminate in cutter-supports 16, comprisingrims 17, which converge to a point toward their free ends and haveseatwebs 18, against which are removably secured cutters 19, consistingof fiat blades having inner compound cutting edges 20, having a distinctor deep concavity at about the center in a transverse direction andgradually sloping off to the points 21. In the opposite direction theedges 2O have convex heels 22. When the cutters are secured to theirsupports, the outer edges abut against shoulders 28, so as to make aconnection.

iiush fitting of each cutter on one side with the adjacent surface ofthe rim. The faces of the cutters which stand flush with theadjacent-rim surfaces are brought together when the shanks Il arepivotally connected and are thereby caused to work closely and make aclean cut, which is started from the points 2O of the blades, owing tothe curvature of the cutting edges described, and continues graduallytoward the heels 22. Vthere the webs terminate at their inner portionsthe metal is cut away to form bevels 24, so as to provide for aclearance of the blades at the points where the said bevels meet thelatter. It is preferred to use screws 25 for securing the blades to thewebs 18, and at any time necessary the said blades may be removed andsharpened or, if too much worn, replaced by others of a similar nature.

'In the operation of the device it is reversible, and in applying thesame the handle-levers l and 2 are opened, as shown by Fig. 2, so as tospace the cutting edges 2O of the blades apart for the reception of thehorn at the point where the severance is to be made. The handle-leversare then drawn toward each other and moved against the resistanceafforded by the horn beingcut ou their fulcrums instituted between theears 5a and the opposite ends of the bars 7. Simultaneously with thismovement the Shanks Il are gradually moved forward with an easy motion,owing to the interposition of the antifrictionrollers 9, which tend toforcefully throw the Shanks regularly together without any shiftingmovement or slip which might arise from a strain brought solely to bearon a pivotal This action continues until the parts are in the conditionshown by Fig. l, when the cutters will have entirely severed thehorn.Byapplyingacomparatively-small amount of power on the grips 3 of thehandlelevers l and 2 the cutters, through the Shanks holding the same,will exert a strong leverage, owing to the connection and arrangement ofthe several parts. The oppositelydisposed bars 7 hold the moving partsin close operative relation and brace the samein their action.

In Fig. 5 a part of one of the heads 4 is shown, and those partscorresponding to the ears 5, as heretofore described, are thickened andformed with slots 26 to movably receive the terminals l2 of the shanks11, and thereby afford a better or strengthening support for theconnecting-rivets.

Many other advantages will appear from time to time to those using theimproved implement, and variations in the proportions, size, and minordetails of construction may be resorted to without departing from thespirit of the invention.

Having thus described the invention, what is claimed as new isl. In adehorning implement, the combination of handle levers, shanks pivotallyattached to the handle-levers and having cutters thereon, said shanksbeing crossed and pivotallyconnected to each other, and transverse barsto which the handle-levers are pivotally connected, the shanks havingmovement between the bars.

2. In a dehorning implement, the combina' tion of handle-levers, a pairof bars between which the handle levers are fulcrumed, shanks pivotallyattached to the handle-levers and having cutters connected thereto, andan antifriction connection between the Shanks and the bars.

3. In a dehorning implement, the combination of handle-levers, a pair ofbars to which the handle-levers are f ulcrumed and extending'transversely of the implement, Shanks pivotally attached to the leversand having guide-slots therein, cutters supported by said Shanks, thelatter being pivotally connected, and antifriction-rollers held by thebars and movable in the guide-slots of the shanks.

4. In`a dehorning implement, the combination of a pair oftransversely-extending bars, handle-levers pivotally connected thereto,pivotally-attached Shanks provided with slots and having ends movablyattached to the said handle-levers, cutters supported by the oppositeextremities of said Shanks, and antifriction devices carried by the saidbars and movable in the slots of the shanks.

5. In a dehorning implement, the combination of handle-levers, a pair ofbars to which said handle-levers are pivotally connected, havingspace-lu gs in reverse position thereon and carrying oppositelydisposedantifriction-rollers, pivoted shanks having terminals thereof movablyattached to the said handlelevers and provided with guide-slots in whichthe antifriction-rollers are fitted, and cutters supported by the saidShanks beyond the pivotal point of the latter.

6. In a dehorning implement, the combination of handle-levers, pivotedshanks supporting cutters and having terminals applied to opposite facesof the handle-levers in mov- `able relation thereto, and a pair oftransversely-extending bars to which the handlelevers are fulcrumed, theshanks having movement between the bars and the latter holding the partsrelatively spaced.

In testimony that I claim the foregoing as my own I have hereto 'affixedmy signature in the presence of two Witnesses.
